Hello!
I tried to resize an xfs filesystem on 64bit 2.6.30 kernel
using 32bit userland, and that does not work, in dmesg I see:
ioctl32(xfs_growfs:24426): Unknown cmd fd(3)
cmd(400c586e){t:'X';sz:12} arg(ffa56df4) on /mnt
ioctl32(xfs_growfs:24427): Unknown cmd fd(3)
cmd(400c586e){t:'X';sz:12} arg(ff991254) on /mnt
so apparently there's no compat_ioctl layer for these ioctls.
Are there any plans to add these? :)
Are you sure you're testing 2.6.30? The copat ioctls were added in
2.6.28.
What command-line flags were you using, Michael ?
I just tried a simple "xfs_growfs -d" here, and it worked fine.
This is 2.6.31-rc7-64bit on top of a 32-bit userland.
Damn. I rebooted to 2.6.27 to test something unrelated, forgot
about it, and later tried xfs_growfs -d, which failed as per above.
And yes indeed, in 2.6.30 everything works as expected.
Please excuse me for the noise.
